Yes, printers only. ... > What smart scheme can we drum up to find out systematically what colour > adjusting we should use? Good question. What you would normally be interested in is an end-to-end colour transformation from pictured objects to printouts that is as closely an identity as possible. This implies that the colour adjustments depend not only on the printer and driver you use, but also on the scanner or camera. This makes things a bit difficult. It becomes even more difficult, if the camera uses automatic white balancing, and you are taking pics of uni-colour objects... But there seem to be some observations that hold generally. From my (few) tests, and from the gimp-print docs, gimp-print with Epson printers throws more ink at the paper than it should. To compensate this, reduce density, or tweak contrast and brightness. ... > chipless Jettec cartridges are no longer available.

So I thought of buying ink in bottles, and then just refilling the empty cartridges. As for the chip, the Epson printers themselves can program it. What a shame that escputil does not yet support this! But the old trick with swapping cartridges should still work: Replace empty cartridge with full one as per handbook, then swap back, but without telling the printer, and it will program the empty cartridges to "full", independently of whether there is ink in them or not... ... > > - AFPL Ghostscript 7.04 puts some object files into the wrong ... > Why didn't you just install the ghostscript 7.05 package for your > distribution? It's been GPL for months now. Yes, but my distribution is quite old (SuSE 7.3), and I had been using AFPL for a long time before, because it did things that were impossible with GNU gs - don't remember what it was. > > - I still have to configure IJS. > > What's that? (Excuse ignorance) What I understand from the gimp-print doc says that stp will be discontinued shortly, and then IJS is expected to take over. IJS is an effort to have the printer-specific parts of a PS printer driver separated from gs. This will make it easier to add device-specific drivers later without any changes to gs. IJS also runs as a separate process. What I now use is a combination of AFPL Ghostscript (only for displaying PS on screen), and the Epson IJS driver for printing via the IJS device from Ghostscript. BTW, although the docs recommend not to configure IJS manually I did it, and it was not too complicated, thanks to the excellent README that comes with the GS part of gimp-print. BTW, I have a vague suspicion that the person who calibrated the Epson drivers for gimp-print owns shares in the company making the ink. I just found that on plain paper a setting of Gamma=1.3 and Density=0.7 works fine for me, which means that the defaults comparedly soak the paper in ink...
